CABLE-G RIP.

SPECIFICATION forming part of Letters Patent No. 443,392, dated December 23, 1890.

Application filed June 18, 1890. Serial No. 355,856. (No model.)

To aZZ whom, it may concern.-

Be it known that I, ELIJAH DAINTY, of Coal Bluff, in the county of \Vashington and State of Pennsylvania, have invented a new and Improved Cable-Grip, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved cable-grip which is simple and durable in construction, very effective when in use, adapted to reduce the strain 011 the cable and car to a minimum, and arranged to easily pass over the cable-sheaves without displacing the cable.

The invention consists of two pivoted members, of which one is to receive the cable and the other is adapted to clamp the cable in place on the first member, and a chain or rope connected with one of the members and passing through an eye on the other.

The invention also consists in certain parts and details and combinations of the same, as will he described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied, parts being shown in section. Fig. 2 is an enlarged side elevation of the improvement. Fig. 3 is a transverse section of the same, and Figs. 4 and 5 are perspective views of the shoes.

The improved cable-grip A is provided with two members B and O, pivotally connected with each other at D at their lower' ends. The member B is provided with a recessed offset 1*), in which is fitted a longitudinally-extending shoe F, (shown in detail in Fig. 5,) and adapted to receive the cable G, serving to propel the car H, connected by the cable-grip with the said cable, as hereinafter more fully described. The cable G is clamped into the shoe F by a shoe I, held in the other member C, so that when the latter is drawn toward the member B the shoe I passes onto the cable and clamps the latter firmly onto the shoe F.

In order to hold the shoe F in place, the latter is provided at its ends with flanges F, adapted to pass over the edges of the member 13, and the said shoe is also provided with an outwardly-projecting pin F arranged near its middle and passing through a suitable aperture in the offset E. A conical pin F projects from the outer end of the pin F and extends into a countersunk aperture form ed in the back of the offset E and adapted to be filled with molten metal, engaging the conical pin F so as to lock the shoe F in place in the offset. E. The other shoe I is also provided on its ends with flanges 1', adapted to pass over the edges of the member 0, and pins 1 and 1 similar to the pins F and F project from the said shoe I, and are locked in the members C by Babbit metal, similarly to the shoe F. In order to take the strain off the pivot D, the member 0 fits into a notch B, formed on a flange B arranged on the face of the member B, as is plainly shown in Fig. 2. The free end of the member 0 is connected with one end of a chain J, passing through an eye or loop K, formed on the free end of the member B, so that when a pressure or pull is exerted on the said chain J the member 0 is drawn toward the member 13, whereby the shoe 1 clamps the cable G firmly into the shoe F. The chain is provided at its other end with a clevis L, connected by a pin N with the usual draw-bar secured on the car H, as is plainly illustrated in Fig. l.

The device is used as follows: The clevis L of the chain J is fastened to the draw-head of the car H, and then the two members 13 and C are opened, so as to be easily straddled over the cable G, the chain J then being disengaged from the eye or loop K. As soon as the cable G has passed into the shoe F, the operator closes the two members B and O, at the same time passing the slack chain J through the eye K, whereby the cable G is firmly engaged between the two shoes F and I. The forward movement of the cable G moves the two members from the car H, so that the chain J is drawn taut and the load is propelled forward. Now it will be seen that the heavier the pull on the chain J the tighter the member C is drawn to the member B, thereby very firmly clampingthe cable G between the shoes F and I. When the car arrives at its destination, the operator disengages the chain J from the car H by first pulling outthe clevis-pin N and then throwing the chain out of the eye K, so that the two members open and the grip drops off the cable. It will be thus seen that the cable-grip can be very readily applied on the cable to propel the cars or removed from the same whenever desired. When the shoes I or I are worn out, they can be easily replaced by new ones by first cutting, out the Babbit metal around the pins F or 1*, so that the shoes can be removed from the respective members and replaced by new ones titted onto the members, as previously described. As the lower parts of the two members I) and C are rounded oil, the clip readily travels over the grooves in the sheaves supporting the cable, as is plainly shown in Fig.1. As the entire load of: the car operates to hold the grip in place on the cable, slipping is prevented.

The device is not in the least cumbersome, is very simple and durable in construction, and can be easily handled.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A cable-grip comprising two members pivoted together at one end, and of which one member is adapted to receive the cable and the other is adapted to clamp the cable in place on the iirst member, and a chain or rope connected with one of the members and adapted to pass through the other member, substantially as shown and described.

2. A cable-grip comprising two members pivoted together at their lower ends, shoes held in the said members, of which one is adapted to press the cable onto the other, and a chain or rope connected with the free end of one oi the members and adapted to pass throughv an eye on the free end of the other member, substantially as shown and described.

3. A cable-grip comprising two members pivoted together at their lower ends, shoes held in the said members, of which one is adapted to press the cable onto the other, a chain or rope connected with the free end of one of the members and adapted to pass through an eye on the free end of the other member, and means, substantially as shown and described, for connecting the said chain with the car to be propelled, as set forth.
